The 32-year-old 'Mirrors' singer - who tied the knot with the 'Total Recall' actress at a lavish ceremony in southern Italy in October - believes marriage suits him and admits he can't wait to spend the rest of his life with his ''best friend.''
The former N-Sync star told 'The Ellen DeGeneres Show' on Wednesday (24.04.13): ''Every once in a while I can catch a glimpse of her when she doesn't see me looking and I have this moment where I'm like if you never make a good decision...if you only make bad decisions for the rest of your life. You made one really good decision.
''Because she's just like...it's nice marry your friend. It's nice to marry your best friend. It suits me.''
Jessica previously revealed that her favourite thing about being married is being able to call Justin her husband.
The 31-year-old actress said: ''It feels like nothing's changed, and yet, everything's changed.
''It's like that intangible thing, you can't quite put your finger on it. But I guess the idea of having a sort-of partner in crime, and the word 'husband,' is pretty amazing.''
